There are two ways I know of starting to work in the round and the one that seems to be recommened most often these days is to use an adjustable ring (sometimes called a magic ring). You'll find lots of tutorials online showing how to do this, but personally, I've never liked using it. When I learned to make amigurumi I used the simpler technique of making two chain stitches, then working into the first chain, which I'll describe in more detail below. When I first heard about the adjustable ring I tried it out, but I didn't find it as easy, or as secure, as my normal method.
Obviously, you should use whichever technique works best for you, but if you're new to making amigurumi, or if you've tried my normal method and not been entirely happy with it, I thought I'd set out exactly how to do it to make it work perfectly. All the instructions are set out for right-handed crocheters (sorry about that left-handers - despite being left-handed myself, I learned to crochet right-handed and that's the only way I know how to do it).
So, most of my patterns start like this (written in US terms, see below for the UK version):
Round 1: Ch 2, work 6 sc into 1st ch - 6 st.
And here is exactly how to do that:
1. Make a slip knot (you’ll need this to start any crochet).
the end of the yarn is on the right-hand side in the next three photos.
2. Put the slip knot on your hook, making sure the short end of yarn is to the right, you'll be working with the rest of the yarn with your left hand.
3. Chain 2 (to chain: yarn over hook, pull through loop on hook).
4. Start working into the first chain. Each chain stitch is made up of two 'lines' with a 'bump' on the other side. You need to push your hook between the two lines and underneath the bump. Work a single crochet stitch (sc in US terms; double crochet, or dc, in UK terms): insert hook into chain stitch as described, yarn over hook, pull through stitch, yarn over hook and pull through both loops on hook.
Since the first chain was made from the slip knot, it will expand as you work into it.
5. In this case the first round is made of 6 sc (most amigurumi start with 6 stitches, but be sure to check the pattern). As you continue to work the stitches you should work over the tail of yarn you started with. You won't be able to do this on the first sc/dc, but after that it should be no problem. Hold the tail of yarn over the hook after you've inserted it through the chain, pull the yarn through and continue with the stitch as normal.
The tail of yarn held over the hook (the working end of yarn is loose above the hook).

6. Once you have completed the six stitches, it should look like this:
7. Pull the tail of yarn to close the hole in the centre.
8. Don't worry if the hole doesn't look completely closed. Work the next round (in the photo below I have worked two stitches in each stitch of round 1 to increase from 6 to 12 stitches), then pull the tail of yarn again. The hole should close completely and be secure.

I hope that helps, let me know if that makes it clear or if you have any questions.
